Mar 1st, 2015 | By

David Joyce has kindly allowed this investigation into his genetic origin to be published.  It was written by Dr. Tyrone Bowes of Irish Origenes. INTRODUCTION A simple commercial ancestral Y chromosome DNA test will potentially provide one with the names of many hundreds of individuals with whom one shares a common male ancestor, but what

Autosomal DNA is that we inherit in equal parts from our parents who in turn inherited it from their parents.   Therefore for each generation we go back the number of ancestors who contribute to our DNA doubles.  It therefore follows that our siblings should have a similar mix of DNA that we do although not

Jul 19th, 2014 | By

There are two types of YDNA markers that can be tested for.   Familytree DNA does both types of tests but you must test for STR markers first in order to then have the SNP testing done.   STR tests can be for 37, 67 or 111 markers but what exactly does that mean? When we test

For those entering the wonderful world of DNA Genealogy there are a bewildering array of different companies with unshared databases so testing with one means that you may be missing connecting with potential matches because they have tested with a different company. There is one place where you can share information with people who have
